Nintendo Wii is the fastest selling home console in the US, with PlayStation 3 selling slower than the original Xbox and only slightly faster than Nintendo's old GameCube.
You might have noticed in the May NPD report that the Nintendo Wii had surpassed 20 million units in the US, officially becoming the fastest selling home video games console in the region.
At the same 31 month mark in April 2003, the PlayStation 2 had achieved 17,360,000, whereas the Nintendo Wii has achieved 20,203,581, according to numbers provided by the NPD Group
After 31 months on the market the Xbox 360 had achieved 10,267,000 units, with the console now reaching 15,240,286 after 43 months. This compares favourably to Microsoft's first Xbox effort, which reached 8,901,402 units at 31 months and 12,200,000 after 43.
As for the PlayStation 3, Sony's latest console is now at 7,749,396 after 31 months on the US market. This is less than the original Xbox and only slightly larger than the GameCube in May 2004 (7,473,241). When compared to the PlayStation 2's 17,360,000 it's an especially sorry sight, emphasising the need for a PS3 price-cut, which is expected in August.
